Question

In color films, there are separate layers of
photosensitiveemulsion for each of the three primary colors of
emitted light(red, blue, and green). The process of film exposure
is again basedon absorption of light energy, but now each layer is
treated toreact to only one-third of the spectrum. For example,
thered-sensitive emulsion is specially treated to react to light
onlyin the portion of the visible spectrum that includes
longerwavelengths. When a single photon of energy 2.89×10−19 strikes a color film, in what layer of
emulsionwill it be absorbed?
